Integer overflow in the LZO algorithm variant in Oberhumer liblzo2 and
lzo-2 before 2.07 on 32-bit platforms might allow remote attackers to
execute arbitrary code via a crafted Literal Run.
Author | Note |
---|---|
alexmurray | grub2 has a vendored copy of minilzo which is part of lzo2 so likely any vulnerabilities that affect lzo2 may also affect minilzo in grub2 and hence grub2-signed |
mdeslaur | grub2 since bug 1911440 now pulls in the system lzo2 when building, so focal+ is fixed grub2-signed on bionic now ships the grub binary built on a later release, so it is not vulnerable to this CVE |
